Question

When the keyboard appears, the Ionic 2 form smoothly slides upwards

I am currently working with the most recent version of Ionic 2. In my code, I have a

<ion-content padding><form></form></ion-content>

containing a text input. However, when attempting to enter text on an Android device, the keyboard pushes the entire page upwards.

HTML File

<ion-content class="login-screen" padding>
  <form (ngSubmit)="login()" novalidate>
    <ion-list>
      <ion-item>
        <ion-label fixed>Username</ion-label>
        <ion-input type="text" name="username" [(ngModel)]="username" required></ion-input>
      </ion-item>
      <ion-item>
        <ion-label fixed>Password</ion-label>
        <ion-input type="password" name="password" [(ngModel)]="password" required></ion-input>
      </ion-item>
    </ion-list>
    <button ion-button full type="submit">Login</button>
  </form>
  <button ion-button clear full outline type="button" (click)="openModal()">Forgot Password?</button>
</ion-content>

Are there any solutions to this issue?

Answer №1

The upcoming RC4 version will address all of these issues. To prevent scrolling when an input is focused, include the following in your configuration object within the @NgModule:

...
imports: [
    IonicModule.forRoot(MyApp, {
        scrollAssist: false, 
        autoFocusAssist: false
    }),
    ...
],
...

You can find a detailed explanation of these properties here:

By default in Ionic 2, features such as 'scrollAssist' and 'autoFocusAssist' are implemented to handle keyboard overlay and focus on input elements. These features can be toggled using config switches.

To prevent the browser from pushing content up and allow the keyboard to slide over without affecting existing content, you can use the ionic-plugin-keyboard:

this.platform.ready().then(() => {
    StatusBar.styleDefault();
    Splashscreen.hide();

    Keyboard.disableScroll(false); // <- like this

    // ...

UPDATE

As @Luckylooke mentioned in the comments:

Keyboard.disableScroll() supports ios and windows platforms.

UPDATE II

In Ionic 3.5.x, there are still some keyboard issues. The following configuration provides better UI/UX results compared to defaults:

@NgModule({
    declarations: [
        MyApp,
        //...
    ],
    imports: [
        //...
        IonicModule.forRoot(MyApp, {
            scrollPadding: false,
            scrollAssist: true,
            autoFocusAssist: false
        })
    ],
    bootstrap: [IonicApp],
    entryComponents: [
        // ...
    ],
    providers: [
        // ...
    ]
})
export class AppModule { }

With scrollAssist: true, we prevent input from being hidden by the keyboard near the bottom of the page. Additionally, setting scrollPadding: false avoids strange bugs related to white space after hiding the keyboard.

There seem to be some issues with inputs and forms scrolling, as discussed here. I suggest waiting for the next RC release to address this issue, as it is not due to your code but rather an Ionic bug.

Here is a method that should be added to the .ts file on this particular page:

ionViewWillEnter() {
  this.content.resize();
}

The issue I am facing is when the keyboard is called on this page, and then returning to the previous page causes the entire page to appear. I am attempting to address this by utilizing the mentioned method in Ionic2.

To successfully implement this feature in your IonicModule within app.module.ts, you simply need to incorporate the following properties. This method has been proven effective for me.

IonicModule.forRoot(MyApp, {
      scrollAssist: false, 
      autoFocusAssist: false
    })

Access the iOS workspace within the iOS platform of your Ionic project and implement the following method in MainViewController.m:

/////////////--------------------------//////////////
/*
 *Description: This method is triggered by the keyboardWillHide selector from the notification
 */
-(void)keyboardWillHide
{
    if (@available(iOS 12.0, *)) {
        WKWebView *webview = (WKWebView*)self.webView;
         for(UIView* v in webview.subviews){
            if([v isKindOfClass:NSClassFromString(@"WKScrollView")]){
                UIScrollView *scrollView = (UIScrollView*)v;
                [scrollView setContentOffset:CGPointMake(0, 0)];
             }
          }
     }
}

Invoke the above method in viewDidLoad using NotificationCenter:

- (void)viewDidLoad
{
    [super viewDidLoad];

    /**
     * Register to observe notifications for when the keyboard will hide
     */

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillHide)
                                                 name:UIKeyboardWillHideNotification
                                               object:nil];
}
